HINGE.

SPECIFICATION forming part of Letters Patent N o. 696,028, dated March25, 1902. Application filed March 25, 1901. Serial No. 52,735. Nomodel.)

T a/ZZ whom, may concern:

Be it known that I, CHARLES H. FOSTER, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented certain new and useful Improvements in Hinges for SwingingDoors, of which the following is such a full, clear, and exactdescription as will enable any one skilled in the art to which itappertains to make and use the same, referencebeing had to theaccompanying drawings, forming part of this specification.

The object of my invention is to construct a hinge for a gravity-closingswinging door which will swing in either direction and in which the rearedge of the door will fit close to the rear jamb and also to providemeans for holding the doorin its closed position until an appreciableamount of pressure is brought to bear against it and also to prevent itsrepeated swinging to and fro after it is released from its openposition.

My invention consists in part in the combination, with a door and itsrear jamb, lintel,

and sill, of an upper hinge between the upper yedge of said door andsaid lintel and provided l with a single pivot and a lower hinge bef-'tween the lower edge of said door and said sill and provided with twopivots, said upper hinge turning at a point farther from the rear ,jambthan said lower hinge.

My invention also consists in certain other novel features and detailsofconstruction, all of which will be describedin the followingspeciiication and pointed out in the claims affixed hereto.

In the accompanying drawings,which illustrate the usual form of doorwith my invention applied thereto, Figure 1 is a view on a reducedscale, partly in elevation and partly in section, showing the doorclosed. Fig. 2 is a top plan view of the fixed part of the lower hinge.Fig. 3 is a bottom plan view of the movable part of the lower hinge.Fig. 4 is a side view of the movable part ofV the lower hinge. Fig. 5 isa section on the line 5 5 of Fig. S. Fig. 6 is a view similar to Fig. 1,but showing the open door. Fig. 7 is a top plan view'of the completeupper hinge, the top part of the fixed member being broken away tobetter show the remaining parts; and Fig. 8

is a section on the line 8 S of Fig. 7 looking in the direction of thearrows.

Like marks of reference refer to similar parts in the several Views ofthe drawings.

10 is the door, 11 the rear jamb, 12 the lintel, and 13 the sill, all ofthe usual form.

The lower hinge is placed between the lower edge of the door 10 and thesill 13 and is formed of a fixed part 14 and a movable part 15. Thefixed part 14 is preferably mortised into the sill 13 and is providedwith an upwardly-extending portion 16,which is secured to the rear jarnbl1 by means of screws 17 or in any other suitable way. The movable part15 is secured to the lower edge of the door 10, preferably by means ofscrews 18, passing through holes 19 in the said movable part 15. In thefixed portion 14 of the lower hinge are formed two curved grooves orguideways 20, at the rear end of each of whichis formed a recess 21,extending outwardly. On the lower face of the movable part 15 of thelower hinge are formed two oblong bearings 22, adapted to rest in therear ends of the grooves 20 and recesses 21. The above-described form ofhinge is not broadly claimed in the present application, as the same iscovered by my copending application, Serial No. 47,391, iiled February15, 1901. The bearings 22 are such a distance apart that they cannotboth slip forward into the grooves at the same time.

On the lower face of each of the bearings 22 is formed a roundedprojection 23, which rests on the bottom of the grooves 20, and thusreduces the friction when the hinge is moved.

The upper hinge is formed of a fixed part 25 and a movable part 26.' Thefixed part 25 is preferably secured to the rear jamb 11 by means ofscrews 27, and the movable part 26 is preferably secured to the top edgeof the door 10 by means of screws 2S, passing through holes 29 in thesaid movable part 26. Carried by the movable part 26 is a spring-.tongue30, on which is carried a bearing-pin 3l. This bearing-pin 31 passesthrough an opening in a plate 32, preferably carried by the fixed part25 of the hinge. Journaled in the end of the spring-tongue andprojecting beyond the rear edge of the door is a roller 33. When thedoor is in its closed position, the roller 33 rests in a groove 34 inthefixed part 25 of the hinge. The roller 33 is adapted to travel on acurved track 35, projecting from each side of the fixed part 25 of thehinge. The ends of the track 35 are curved, as shown at 36 in Figs. 5and 7. In order to prevent the movable part 26 of the hinge from beingraised from the top edge of the door with the spring tongue 30, the saidpart is provided with two downwardly-projecting arms 37, carrying across-piece 38, on which is formed a pin 39, adapted to enter the rearjamb of the door lO.

The operation of my door is as follows; When the door is in its closedposition, the roller 33, carried by the spring-tongue 30, rests in thegroove 34 in the fixed part 25 of the upper hinge, thus preventing thedoor from being opened until a considerable pressure is brought to bearagainst it. As soon as sufficient pressure vis brought to bear againstthe door the roller will be forced up out of the groove 34 and to oneside of the track 35, the spring-tongue 30 bending suciently to allowthis. The roller then moves on the track 35. The tension thus brought tobear on the spring-tongue 30 tends to lift the door, and thus relievethe pressure between the parts of the lower hinge. As the door movesupon one of the bearings 22 the movable part of the lower hinge willturnin the corresponding recess 21 in the fixed part of the lower hinge,the other bearing, 22, passing along the opposite groove or guideway 20.As the pivot 3l of the upper hinge is farther from the rear jamb of thedoor than the bearings 22 of the lower hinge, the outer end of the doorwill be carried upwardly, as shown in Fig. 6, thus causing the door totend to return to its closed position. In case the door is opened to apoint at right angles to its closed position the roller 33 will pass oifthe track 35. When the door is released, the roller will be forced uponto the track 35 upon striking the curved end 36, thus tending tolessen the momentum of the door, so that when it reaches its closedposition it will be readily stopped in such position by the roller 33dropping into the groove 34, thus preventing the repeated swinging toand fro of the door. In doors ot' this class it is usual to provide noraised sill, the floor itself serving as a sill. Therefore where I haveused the term sill I want to include a ioor serving as a sill.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, issl. The combinationwith a door, of a rear j amb, a lintel, a sill, a hinge situated betweenthe upper edge of said door and said lintel and provided with asinglefpivotand a hinge situated between the lower edge of said door andsaid sill and provided with two pivots, said upper hinge having itspivotal point at a greater distance from the rear jamb than said lowerhinge.

2. A hinge for doors or the like consisting of a xed part and a movablepart, one of said parts being provided with a pair of bearings, and theother of said parts being provided with a pair of intersecting curvedguide- Ways having a recess formed atthe outer sides of the rear endsthereof.

3. A hinge for doors or the like consisting of a ixed part and a movablepart, one ot said parts being provided with a pair of intersectingcurved guideways, and the other of'said parts being provided with a pairof bearings having rounded projections formed on the faces thereof.

4E. In a hinge for doors or the like, a fixed part, a movable part, atrack carried by one of said parts, and a spring-mounted member carriedby the other of said parts and traveling on said track.

5. In a hinge for doors or the like, a fixed part, a track carried bysaid iixed part, a movable part, and a spring-mounted member carried bysaid movable part and traveling on said track.

6. In a hinge for doors or the like, a fixed part, a movable part, atrack carried by one of said parts, and a spring-mounted roller carriedby the other of said parts and traveling on said track.

7. In a hinge for doors or the like, a fixed part, a track carried bysaid fixed part, a movable part, and a spring-mounted roller carried bysaid movable part and traveling on said track.

8. In a hinge for doors or the like, a fixed part, a track carried bysaid fixed part and having a recess in the central portion thereof, amovable part, and a spring-mounted roller carried Vby said movable partand traveling on said track.

In testimony whereof I have hereunto set my hand and affixed my seal inthe presence of the two subscribing Witnesses.
